Cursing on the internet. the digital spells are remaining for ever

some wiccan told me. that is ridicilus to make spells online in the internet.
i wondering why.
the spititual world is manifesting upon the world of objects.
and the world of the objects effect the spiritual world (according to Plato for example).
The internet is a part of the world of the objects so a curse or spell in the internet is the same
effective as any other spell.
Actually is not the same effective but more effective. because the digital spells are remaining for ever.
